| Description |
| Reconstruction of harmful events or forensic analysis is not possible if audit records do not contain enough information. At a minimum, the organization must audit the full-text recording of privileged commands. The organization must maintain audit trails in sufficient detail to reconstruct events to determine the cause and impact of compromise. |

| Verify SLEM 5 generates an audit record for all uses of the "newgrp" command with the following command: > sudo auditctl -l | grep -w '/usr/bin/newgrp' -a always,exit -S all -F path=/usr/bin/newgrp -F perm=x -F auid>=1000 -F auid!=-1 -F key=privileged-newgrp If the command does not return any output, this is a finding. Note: The "key=" value is arbitrary and can be different from the example output above. |
| Fix Text (F-65073r996714_fix) |
| Configure SLEM 5 to generate an audit record for all uses of the "newgrp" command. Add or modify the following line in the "/etc/audit/rules.d/audit.rules" file: -a always,exit -F path=/usr/bin/newgrp -F perm=x -F auid>=1000 -F auid!=unset -k privileged-newgrp To reload the rules file, restart the audit daemon: > sudo systemctl restart auditd.service or issue the following command: > sudo augenrules --load |
